Answer:
$10
Step-by-step explanation:
Subtract the price of the keychain, $7, from the total to find the price of the 3 t-shirts:
$37 - $7 = $30
The 3 t-shirts cost a total of $30.
We assume all t-shirts have the same price.
price of 1 t-shirt = $30/3 = $10
Answer: $10
3)Principal Amount = P = $7200
Interest rate = r = 4% = 0.04
Time = t = 8 years
Formula for compounding is:

Using the values, we get:

Therefore, the compounded amount will be $9853.70
4)Principal Amount = P = $7200
Compounded Amount = A = $9853.70
Interest Earned = Compounded Amount - Principal Amount
So,
Interest Earned = 9853.70 - 7200 = $2653.70
Therefore, $2653.70 will be earned as interest over a period of 8 years.
for any fraction a/b, the decimal format of it is just a ÷ b.
A)
is the number rational?
well, a rational number is one we can write as a ration or fraction, well clearly is a fraction so it is rational.
B)
can it be written as a repeating/recurring decimal? well, 9/20 is 0.45, so -9/20 is -0.45, no repeating decimal like 0.454545......... , just a plain vanilla -0.45, so nope.
C)
is it less than -0.4?
well, let's recall that for the negative side on the number line, the closer to 0, the larger the number, so then -1,000,000 is much smaller than -1, because -1 is closer to 0.
who is closer -0.4 or -0.45?
|--------------------- -0.45 -------- -0.40 ------------------- 0 --------------- 1 -------------------|
so, -0.45 is farther from 0, and therefore is smaller than -0.4, so yes.
Answer:
Negative
Step-by-step explanation:
It's negative because my math teacher said so a few years ago. Sorry for the not so great explanation... I didn't pay attention that day.
The answer to an absolute value must be positive
here are examples of simple ones
ex1:|-5|=5
ex2:|-3|=3
